To all whom, it may concern:

Be it known that I, JOHN AUSTIN YATES, a citizen of the United States ofAmerica, residing in the town of Rosebank, county of Richmond, and Stateof New York, have invented certain new and useful Improvements in Cementand the Process of Making Same, of which the following is aspecification.

My invention relates to a new and useful composition of matter and to aprocess for making the same. The new composition is adapted-for use asinsulating-cement,'and particularly for use as the base of anincandescent-light bulb.

My composition consists of the following ingredients, combined in theproportions stated: rosin, thirty-two er cent. m'nc oxid, twenty percent.; marb e-fiour, forty-eight per cent. These ingredients areordinary articles of commerce, except that the rosin I prefer to use isthat known in commerce as white rosin. The cement consisting of theabove-named insulating electric wires from each other and inwithstanding application of heat up to the point ordinarily met with inservice.

now making the cement. heat I melt the rosin oxid and bring and then addBy the app ication of the mixture to a liquid form, the marble-flour. Ofcourse ingredients has been found to combine desired results in thenature of proceed to explain the rocess ofand then add the zinc duringthe mixing of the ingredients the matter is thoroughly mingled byagitation. The composition is then applied to whereit may be useful andallowed to cool.

What I claim, and desire to secure by Letters Patent, is

1. A composition of matter consisting of rosin, zinc oxid, andmarble-flour.

2. A composition of matter consisting of thirty-two parts of rosin,twenty parts of zinc oxid, and forty-ei ht parts of marbleflour,combined under t e action of heat.

3. The rocess of making cement which consists o reducing rosin to aliquid under the action of heat, mixing zinc oxid therewith and reducingthe mixture to a liici uid under the action of heat, mixingmarbleourtherewith, and allowing the mixture to cool.

4. The process of, making cement which consists of reducin thirty-twoarts of rosin to a liquid .under t e action of eat, mixing twenty partsof zinc oxid therewith and reducing the mixture to a liquid under theaction of heat, mixing forty-eight arts of marble-flour therewith,- andallowlng the mixture to cool.

In witness whereof I have hereunto set my hand this 26th day of January,1906.
